n the monatomic nitriles, Phe monatomic nitriles may hey re- 
garded as primary monamines, the three atoms of hydrogen in ammonia 
being replaced by one atom of a triatomic radical. L. Henry has shown 
that this view is supported by several new and interesting facts. Thus 
acetonitrile, (©,H,)”N, readily unites with dry bromhydric and iodhy- 
acids with production of intense heat. The resulting salts are solid 
stalline white bodies, soluble in alcohol but insoluble in ether. They

cyanic acid and sulphocyanid of ethyl may also be referred to the type 
of ammonia, like the corresponding cyanic acid and cyanid of ethyl. 
The sulphocyanids of ethyl and allyl combine readily with dry bromhy- 
dric and a de acids, giving white crystalline ee ia by

5. On the constitution of mellitic acid.—B x ue ere biel 
found that mellitic acid is six-basic and has ie constitution of benzol, 
in which six atoms of hydrogen are replaced by six of carbonyl, €0,H, 
so that its formula is €,(€0,H),. When heated with lime it is com- 
pletely decomposed into carbonic ‘acid and benzol. With sodium amal- 
gam mellitic acid takes up six atoms of hydrogen and forms the six-basic 
acid, ©€,H,(€0,H),, which, when heated with sulphuric acid, yields a 
four-basic acid, ©,H. (€0H),. This can take up four atoms of hydro- 
— carbonic acid. The final product of these ie san ea is ben- 
ce acid. The authors beg chemists who may possess a stock of mellite 
to supply th them 4 material for their investigation. wi der Chemie
